The invention relates to a narrowband Internet of Things-oriented lightweight security authentication key exchange method, which is used for controlling a terminal needing dual identity authentication, the dual identity authentication is carried out at two authentication levels respectively, two administrators respectively have the authority of opening the two authentication levels and are both configured with keys, and the key exchange method is used for controlling the terminal needing the dual identity authentication. The administrator ID and the key ID are in one-to-one correspondence, the key and the server share a root key K, and bidirectional authentication between the administrator and the server is carried out by using a challenge-response mechanism based on a symmetric cryptosystem, so that the two authentication levels are not opened at the same time, and the administrator carries out identity authentication at the authentication level of the corresponding authority to obtain a door opening passwor
